TONGUELESS WHEEL-CULTIVATOR.

SPECIFICATION forming part of Letters Patent No. 293,030, dated February 5, 1884.

Application filed October 29,1883. No model.)

To aZZ whom it may. concern: Be it known that I, THOMAS B. J EWETT, of Steubenville, in the county of Jefferson and Stateof Ohio, have invented certain new and Cultivators; and I- do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use it, reference being had to the accompanying drawings, which form part of this specification.

My invention relates to an improvement in tongneless wheel-cultivators and it consists- First, in an axle having its ends turned backward at an angle, so that the wheels will be attached thereto at a point to the rear of the front end of the beams. The object of this part of my invention is to so construct the axle that its ends'are turned backward, so as to throw the wheels and the points of draft to the rear of the front ends of the beams, and thus make the draft easier upon the animals.

Second, in an axle having its rear ends turned backward and upward, in combination with the draft-bars, which are applied to the upturned ends, and which draft-bars have the them. The object of this part of my invention is to bring the draitanimals back as near as possible to the front ends of the beams, and so make the draft easier upon them.

Third, in the arrangement and combination of parts, which will be more fully described hereinafter.

The object of my invention is to provide a cultivator which, while it is easier upon the draft-animals, cannot be thrown down, and which is more readily and easily managed by Figure l is a side elevation of a-cultivator Fig. 2 is a plan view of the same. Fig. 3 is a front view. Fig. 5 is a detailed View. Fig. 4 is a detached View of the front end of the beams, showing the slotted plates for attaching them to the vertical portion of the axle.

A represents the curved axle or arch, which, instead of having its ends turned straight outward, has them here bent backward at any desired angle, from B to C, and then has the ends D turned vertically upward, as shown. I do not limit myself to the angle at which the ends of the axles are turned backward, for this may be varied at will, the object being to throw the point of draft to the rear of the front ends of the beams, so as to bring the draft-ani1nals as close to the beams as possible. Another advantage gained by this construction is, that the cultivator cannot be thrown down, as is the case where the ends of the axles extend outward in a straight line with the central portion. Passing through the axle at each end are the pins E, which serve as stops or supports for the draft-rods F, which are passed down over the upturned ends of the axle, as shown. These draft-rods have perforated ears upon their inner sides, and

which are turned horizontally over, so as to stand at right angles to the rods themselves. These rods are held in position upon the upturned ends of the axle by means of the pins G, which are passed through the axle above their upper ends. Secured to or formed as a partof these draftrods, as maybe preferred,

are the spindles H, upon which the wheels I i turn. As here shown,the spindles are simply passed through the draft-rods, and over these spindles are passed suit-able sleeves, J, and upon these sleeves the wheels turn. By taking out the upper pins the draft-rods may be removed from the axle, carrying the wheel with them. After the draft-rod has been removed from the end of the axle, where the spindle is formed as a separate and independent piece, it may be removed from the draftrod and a new one substituted in case of any accidental breakage. It will'be seen that the points of draft are behind the front ends of the beams, for the purpose of bringing the draftanimals as close to the beam as possible,

and thus making the draft easier upon them. WVhere the points of draft are in front of the front ends of the beams, or in a line with them, the cultivator will collapseand fall down, if not sufficieutly held in place. This defect the construction above described entirely overcomes. Secured to the front ends of each one of the beams is a perforated metal plate, 0, which passes over the vertical portion of the axle, and which is supported in place by means of a pin or rod, H, which is passed through the axle, as shown. Upon the top of each one of the beams is secured a metallic plate, I, which has its upper end curved upward, as shown, and a suitable slot made through this curved portion, for the purpose of allowing the beams to be raised freely upward. Suitable pins are passed through the axle above these slotted plates, which prevent any vertical movement of the front ends of the beam upon the axle. The slotsthrough the curved ends of the upper plates are so formed that when the beams are in or resting upon the ground the front end of the slot is bearing against the front side of the axle, and .thus prevents the beam from sinking too far down. The front ends of these plates are curved, as shown, so as to work freely back and forth under the pins which catch over their tops, and which pins serve to prevent the beams from any tendency to turn over. The curve of the front ends of the upper plates is made on a circle from the center of the front ends of the lower plate, so that when the beams are raised and lowered the curved portions of the upper plates will work freely under the pins. lVhen the beams are raised upward, the slotted end of the top-plates moves forward upon the axle until the rear ends of the slots strike against it, and thus serve as stops to prevent the beams from dropping forward, as it would do when the cultivator is left standing. Either.

easier upon the draft-animals than those of 40 the ordinary construction.

Having thus described my invention, I claim- 1. In a wheel-cultivator, an axle having its ends turned backward at an angle, so as to bring the points of draft to the rear of the front ends of the beams, substantially as shown. 2. In atonguelesswheel-cultivator,thecomnation of the axle, having its ends turned backward at angle and then upward, with draft-bars carrying the spindles for the wheels, the draft-bars being applied to the Vertical portions of the turned-up ends, substantially as described.

3. In a wheel-cultivator, the combination of the axle, having its ends turned backward and then upward, with the wheels applied to the upturned ends, substantially as set forth.

In testimony whereof I affix my signature in presence of two witnesses.

THOMAS B. JE\VETT.
